| Abstract: | Isoamyl isovalerate has been synthesized by using sodium hydrogen sulfate as catalyst. The optimized condition are follow: the weight of catalyst is 1.0g, the mole ratio of alcohol to acid is 1.5:1.0, the reaction time is 1.5h and the taking water reagent (toulene) was 10ml ,The esterification yield is 90.3%.The catalyst could be isolated from other matters and repetition use. |
